PHILADELPHIA — A man who spent long hours each day playing video games was convicted Tuesday of killing his 17-month-old daughter when she pulled down his Xbox console.

Jurors rejected arguments that Tyrone Spellman confessed to protect the child's mother.

After a day of deliberation, they convicted Spellman of third-degree murder and child endangerment, which expose him to about 23 to 47 years in prison.

Prosecutors believe he pummeled Alayiah Turman, cracking her skull several times, while her pregnant mother napped in another room on Sept. 7, 2006.
